The architectural program sounds simple enough: Design an art studio inspired by modern architecture. One that "captures the sky" using only sustainable materials. And that is straightforward enough for the clients to build themselves.

Said clients were two artists who wanted their process of "making" to begin with the very bones of their studio. Determined not to disappoint their enthusiastic clients, London-based Threefold Architects designed a long, simple structure based partly on the farmhouse/barn vernacular of the local area. A gabled roof, windows highlighting prairie views, and a bountiful produce garden all reference the rural locale (of Norfolk, United Kingdom). Conversely, all-black exterior cladding, blood-red window trim, and a notable absence of frills meet the mandate for modern design. As for the studio's sustainability program, all building timber was sustainably sourced, rainwater is collected and reused, and electricity is generated via rooftop photovoltaic cells. The heat-absorbing black cladding is actually recycled cellulose fiber, and walls are insulated with wool to retain the heat. Altogether, the studio is carbon neutral in operation.
